WINDOW-SASH-ADJUSTING DEVICE.

Specification of Letters Patent.

Patented Apr. 2, 1912.

Application filed September 15, 1910'. Serial No. 582,140.

. To all whom it may concern:

Be it known that we, ARTHUR G. LINDLEY and NORMAN F. DICKENS, citizensof the United States, both residing at Schenectady, in the county ofSchenectady, State of New York, haveinvented certain new and usefulImprovements in VVindow-Sash-Adjusting Devices, of which the followingis a specification.

The present invention relates to window sash adjusting devices, and hasfor its object to improve their construction and operation, whereby thesashes may-be raised and lowered in the ordinary manner and also swunginwardly into the building for the purpose of safely and convenientlycleaning the outside of windows, or be removed entirely from the framefor repairing, etc., and this without interference in any case from thesash cords and weights of the counterbalancing means.

For a detailed-description of what we believe to be novel and ourinvention. attention is directed to the accompanying description andclaims appended thereto.-

In the accompanying drawings is illustrated one of the embodiments ofour invention, in which- Figure 1 is a vertical section of awindow framefitted'with our invention, the sashes being shown in dotted lines; Fig.2 is a similar view showing the upper and lower sashes swung into thebuilding and resting on the stool cap and floor rests; Fig. 3 is anenlarged detail view showing one of the 1 lower corners of a sash and ahanging strip;

' Fig. 4 is a side view of the same; Fig. 5 is a detail view of the jamb and one of the removable stops and its securing means; Figs. 6 and 7are detail views of the floor rests that support the inner ends of heavysashes when swung into the building; and Fig. 8 shows the details of thesafety hook.

In Figs. 1 and 2 of the drawings is shown a section of a window framehaving sash stops 1, parting strips 1*, pulleys 2, sash cords 3 for theweights 3, sashes 4:, shown in dotted lines in Fig. 1 and full linesinFig. 2, a stool cap 5,and a lintel 6, all of which are or may be ofusual construction.

As our invention contemplates the feature of swinging both the top. andbottom sashes inwardly into the building for the purpose of readily andsafely cleaningthe outside of the window, repairing or removing them,pivoting means are provided therefor. l For convenience that of thelower sash will be referred to first. The sash is or I may be cut awayor rabbeted on opposite sides at its lower corners as best shown in Fig.3. Owing to the character of the view, only one side of the sash isshown, but it is to be understood that the opposite side is or may besimilarly prepared. Mounted in this cut-away portion is a pivot-pin 7which may be of any suitable construction, but for simplicity andreduced-cost a screw is used. To the lower end of the sash cord isattached a flexible connector?) that may be made of chain, cable orwire, or this connecting means-mayextend from the hanging strip to theweight, eliminating the sash cords, as best suits the requirements inany particular case. I In connecting the sash cord with the connector,and assuming for'illustration that the latter is made of wire, it isfirst bent and sharpened as at 10. Itis then inserted into the body ofthe cord and the outside tightly wrapped with fine wire as shown at 11.Owing to the fact that the joint between the cord and the connectorgradually tapers it will readily pass-over the pulley 2 if necessary.The thin flexible v:

connector is used because the lack of space between the ordlnarv sashand wmdow jamb prevents the use of relatively heavy-"cord.

By using the thin connector and thin flat hanging. strips, we areenabled to equip windows of various kinds which are now in use, withoutcutting the frames or the sashes except at the bottom to receive thepivot pins. Of course if the sashes make a very tight fit they may berelieved slightly on,

the sides, but in no case is it necessary to cut or groove the frames, atask which is bothdiiiicult and expenslve.

The lower end of the connector 9 is se-V cured to a flat metal hangingstrip 8 by suitable means, as for example, by, the clip 12 and thehook-likeformation of the con-,

nector' end. The clip may be riveted to the hanging strip or otherwisesecured thereto,

The connector is passed through the eye of the clip and when the desiredadjustment of length of sash cord, position of weight, etc., isobtained, the extra length 'is cut oif and the end turned up as as at 13to form a supporting hook or secured in. some other suitable manner.

The hanging strip 8 may be made of any" suitable material ,having thenecessary strength and rigidity with small cross-secthe sash. The seatfor the pivot is below the mouth of the notch or slot to preventaccidental displacement of the parts. A pin 33 may also be mounted inthe sash above the pin 7 and close to upper edge of the notch 14 toprevent accidental displacement when the sash is being raisedpreparatory to swinging it downward for cleaning or repairing. lVhen thesash is being turned down about the pivot 7, the pin 33 moves out of theopening of the notch 14. and into such a position that it does notinterfere with the removal of the sash, if it is desired to take it out.With the pivot pins in place the sash can be raised and lowered at willand in the same manner as the ordinary window.

The inner sash stop 1, which is fastened to the frame, is made in twoprincipal parts, the upper part being securely fastened in positionwhile the lower part is made removable to permit swinging the sashesinwardly.

Unless means are provided to prevent it, the sash weights will suddenlyraise the bottom of the sash as the top is swung away from the framewhen they overba-lance the load on them. To prevent this a means isprovided that locks or secures the sash weights .in their elevatedpositions while the sash is being swung on its pivots. This lock becomeseffective before the inward swinging movement of the sash is commencedso as to prevent accidents which might take place with large heavywindows, and also insures a fixed and definite position for the sashwhen it is desired to clean the glass or make repairs. The lockingdevice comprises a suitably shaped notch or slot 15 in the hanging strip8 fitted with a safety hook 28 and cooperating with a pin, screw orequivalent device 16 located in the window jamb and therefore fixed inposition. Between the pivot pin 7 and the locking pin 16 the hangingstrip is or may be offset so as to readily engage said pins. These pinsare out of vertical and horizontal alinement as is shown in Fig. 4.

To swing the lower sash inwardly the action is as follows, it beingunderstood that both sides of the sash are alike and similarlysupported: The lower portions of the sash stop are removed and the lowersash raised slightly to clear the stool cap 5, and at the same timemoved inwardly until the looking pins '16 enter and are finally seatedin their cooperating notches 15. As soon as this is done the weights onthe cords are prevented from raising the sash. The top of the sash isthen swung about pivot 7 away from its upright position and down wardinto the building until it assumes the position shown in Fig. 2 and isresting on the stool cap 5, and its floor rests 25 if the weight of thesash makes it necessary to use said rests. This downward movement of thesash causes the safety hooks 28, which are pivotally mounted on thehanging strips 8, to cover the openings of the slots 15 when the lockpins 16 are engaged therein, preventing said lock pins escaping fromtheir engaging slots until the sash is again raised to its normalposition, when the hooks are automatically raised and held out of thepath of the lock pins. This action is best seen in Fig. 8. When the sashis in normal position, the pin 29 mounted stationary in the sashprevents the hook from dropping by bearing on the projection 30. Theopposite projection 31 on the safety hook is also now in the path of thepin 29, so that when sash is moved inward a short distance the hook iscaused to move downward over the slot opening. Owing to the radius ofthe travel of the safety hook being much shorter than that of the sashabout their respective pivots, the projection 31 on the safety hookdrops out of the path of the pin 29 when the sash is swung in. Thedownward movement of the hook is arrested by its coming into engagementwith the pin. 16. The projection 30, owing to its sufficient length, isstill in the path of the pin 29 when the sash is dropped inward, whichallows the pin to raise the hook as the sash is nearing its normalposition. The end 32 is so shaped and is so located with respect to thepivot of the hook 28 that should the pin 16 press against it, there isno tendency to lift the hook but rather to hold it in position to closethe opening of the notch. The weight of the free end of the sash actingthrough the stool cap as a fulcrum forces the pivot pins 7 into theupper end of the slots 14 where they are held by the weight of the sashand are prevented from slipping out by the inclined walls of the mouthsof the slots; see Fig. 2. This same action causes the pins 16 to befirmly seated and held in the slots 15. At this particular time there isan upward thrust on those portions of the strips between the pins, whichcauses the lock pins 16 to act as supports for the sash when inhorizontal position. To restore the sash the free end is raised to itsnormal position, the pins 16. disengaged and the stops remounted inplace.

The arrangement of the pivot pins, hangupper sash inwardly it isnecessary to first move the lower sash as described and then to removethe lower portions of the parting rods 1 which are made in two piecesfor the purpose. The sash is then lowered until it strikes one or morestops 24. These are so set that when the sash engages them the mouth ofnotch 15 will be in position to receive the locking pins l6 carried bythe jamb when the bottom of the sash is moved inward. After this thesash may be restored to normal operating conditions by raising it to anupright position and disengaging the locking pins by pressing the lowerpart of the sash back against the blind-stop.

Referring to Figs, 1 and. 3, it will be noted that the locking pins'16and 16" in the window jamb extend into the path of the sashes and wouldlimit their downward movement. To permit the sashes to be moved to thede sired position, a small piece is cut out of the lower corners of thesashes as shown in Fig. 3, the length of said cut-away portion beingdetermined by the position of the pins and the desired travelof thesashes To swing the sashes inwardly it is necessary, as before stated,to remove the lower portion of the sash stops 1. To permit these stopsto be quickly and easily removed without mar-ring the wood-work,specialsecuring means are provided. The adjacent ends 17 of the sectionsof the stops are connected by dowel pins 23. The jamb 18, Fig. 5, iscounterbored atone or more places to receive screws 22 of suitable shapeand size. Registering with each screw and fastened on the removablesection 19 of the sash stop by a screw 21, is a spring clip 20 havingtwo arms arranged to embrace the head of the screw 22 when forced, overit. These spring clips interlocking with the screws hold the stopsagainst the lower sash, prevent lateral movement thereof, and form asimple yet efiective means for securing the stops. 7

It willbe noted from Fig. 2 that the sloping wall of the upper portionof the slot 14 inthe hanging strip 8 securely locks the sash in itshorizontal position thereby preventing accidental removal. To remove thesash it is sufficiently raised at its free end to cause the pivot 7 toregister with the mouth of the notch, after which a movement of the sashaway from the frame will remove it. The weighted sash cords during thisoperation are held by the locking pins 16 or 16 In using this device onlarge windows the weight of which would be too great for the lock andpivot pins to support across the stool cap, floor rests are provided asshown at 25-Figs. 1, 2, 6 and 7, one on each side .tively unskilledworkman.

of the sash. These supports are made preferably of light metal angle, asection of which is shown at 25 (Fig. 7 and are attached to the sash byscrews 26 (Figs. 2, 6

and 7). In these views the sash is shown in horizontal position withsupports dropped to rest on floor. When the sashes are restored to theirupright position these supports, swinging on the screws 26, assume avertical position, Fig. 1, the legs of the angle extending around andparallel with the inside corners of the sash, with the longer leg of theangle between the jamb and sash. To provide space for the shorter leg ofthe anglefwhen in this position, the sash is rabbeted as shown at 28Fig.6. These supports are applied only to the lower sash, as the upper sashrests upon the lower when in horizontal position (Fig. 2). Thesesupports are made of proper length to allow the stool cap to act as afulcrum for the purpose mentioned, and yet relieve the pins of the extraweight by reaching the floor.

The chief advantage of our improved construction, aside from itssimplicity and low first cost, resides in the fact that it can beapplied to any weighted window wherein the sashes are moved up and downwhether they are new or old, without cutting the window frame or jambsor modifying the sashes except by making small cuts in the lower cornersthereof. This latter operation is so simple that it can be done by arela- Our arrangement does not require any particularly nice fitting oradjusting, and hence can be installed in a short space of time and atsmall expense.
